Update with additional responses Hours after offering his support to the UK in the wake of last night’s terror attack in London, and saying “We are with you,” U.S. President Donald Trump hopped on Twitter again this morning. But this time, it was to scold London Mayor Sadiq Khan. Referencing a statement by Khan in which he told Londoners they would see an “increased police presence today and over the course of the next few days – no reason to be alarmed,” Trump tweeted, “At least 7 dead and 48 wounded in terror attack and Mayor of London says there is ‘no reason to be alarmed!’”

At least 7 dead and 48 wounded in terror attack and Mayor of London says there is "no reason to be alarmed!"

This drew the ire of Labour MP David Lammy who told Trump to “Stop commenting on what has happened in my city. Put your phone down.” He added, “Cheap nasty & unbecoming of a national leader. Sort of thing that makes me want to quit politics on a day like this. Evil everywhere we look.”

This isn’t the first time someone in the Trump family has taken a crack at London’s Muslim mayor: In March, Donald Trump Jr. criticised Khan for saying terror attacks were “part and parcel” of living in a major city in the modern age. Trump Jr. distastefully tweeted a link to a September 2016 article in which Khan made the remarks saying, “you have to be kidding me?!” just moments after the Westminster attacks in March:

In the article, Khan had also said: “I want to be reassured that every single agency and individual involved in protecting our city has the resources and expertise they need to respond in the event that London is attacked.”

Trump also linked last night’s events to the issue of gun control, seeming to take a jab at those who support harsher measures — and perhaps failing to realize that the UK has some of the strictest gun laws in place in the world.

UK laws dictate that guns are dangerous weapons and that the government has a duty to protect the public from their misuse. Gun ownership is considered a privilege, not a right and because of that, gun crimes in the UK attribute to less than 0.2% of recorded crime.

“Do you notice we are not having a gun debate right now? That’s because they used knives and a truck!,” Trump tweeted. The attackers on Saturday night drove a van into pedestrians in London Bridge before stabbing people in Borough Market, killing seven and wounding at least 48.

Do you notice we are not having a gun debate right now? That's because they used knives and a truck!

Earlier today, UK Prime Minster Theresa May told media that the three homegrown attacks that have occurred in the UK in the last 73 days are unrelated and pointed to a trend in “copycat” attacks. She called for more allied international agreements across the internet to prevent the spread of terrorist planning.
